News and Updates

🚨 Major GST System Changes in Action
The transformative GST updates that went live on July 1, 2025, will be put into practical application during the August filing cycle for the July tax period.

  1. Hard-Locking of Auto-Populated GSTR-3B Liability: When filing the GSTR-3B for July 2025 (due in August), the liability in Table 3 will be auto-populated from GSTR-1 and cannot be edited. This necessitates a “first-time-right” approach to GSTR-1 filing.
  2. Three-Year Time Bar on Filing Returns: The deadline to file any pending returns older than three years is now in effect. Businesses should ensure all historical filings are up to date to avoid being barred from filing

This calendar is prepared for the benefits of clients and well-wishers of M/s Kanhaiya Gautam and Associates, Chartered Accountants. This should not be used as substitute for professional advice.  Best efforts are placed to compile these due dates, still we would appreciate if you draw our attention to any inaccuracy.
